CASH REGISTERING AND INDICATING MACHINE.

SPECIFICATION forming part of Letters Patent No. 557,517, dated March31, 1896.

Application filed April 30,1895. Serial No. 547,671. (No model) To allwhom, it may concern.-

Be it known that I, DAVID T. METHVEN, a citizen of the United States ofAmerica, residing at Springfield, in the county of Hampden and State ofMassachusetts,l1ave invented new and useful Improvements in CashRegistering and Indicating Machines, of which the following is aspecification.

This invention relates to improved means for operating the shiftablesupport for the indicator-tags of cash registering and indicatingmachines, whereby after a key has been operated and a tag elevatedthereby and so left the tag may be dropped by means independent of theregistering-keys of the machine.

My invention consists in a tag-support and a lever which engages thissupport, combined with the push-rod and the yoke and the arm appliedthereto and secured in position by set-screws, the arm being providedwith a wedge-like extremity, as will be more fully described hereinafterand claimed.

Reference is to be had to the accompanying drawings, in which- Figure lis an end elevation of a cash registering and indicating machine withthe present improvements applied thereupon, the front part of thecabinet or casing being shown in vertical section. Fig. 2 is arearelevation of the portion of the machine which comprises the parts seenin Fig. 1. Fig. 3 is a horizontal sectional view taken on the line 3 3,Fig. 1, and showing in plan view the relation of certain parts below theline of section. Fig. l is an end view of a part in detail to behereinafter referred to. Fig. 5 is an end elevation illustrating theessentials of the present invention and which will be hereinafterreferred to. Fig. 6 is a plan and horizontal section taken on line 6 6,Fig. 5.

In the drawings, A A represent the keylevers of the cash-registeringmachine, acting as usual, in conjunction with the indicatortags B 13.

0 represents the shiftable support for the tags, having stops or rests afor the lugs Z), which are provided on the stems of the indicator-tags,the operations of which, one relative to the other, are well known.

D represents a key-locking bar pivotally supported at d and having thespring (Z applied thereto for normally maintaining it in its position ofengagement with the rear ex tremities of the several key-levers.

G represents a push-rod having a connection with the key-locking bar andhaving its forward end protruding through the front of the cabinet, asseen at f, the protruding end being provided with the button or knob g.This push-rod has thereon a depending projection g which as the rod isrearwardly pushed to release the key-lever-locking bar snaps past thetrigger it, which is upwardly spring-pressed and remains in engagementwith the tooth ]L2 of the trigger until after the key has been operated.It is understood that in this mechanism there is a dog J, which swingsas one with the rocker-plate K, which is common to all of the keys ofthe bank and moves in unison with any one of such keys. This dog has theoutwardly-spring-pressed toothj, which may recede inwardly within thebody of the dog, which is hollow, as the dog is upwardly swung, actingin the manner of a door-latch, whereby the tooth may assume its positionabove the point of the trigger, and so that when the key-lever isreturned to its normal position and the rockerplate with it the dog willtrip the trigger and allow the push-rod to return to itsforwardlyprojected position, which occurs in consequence of the spring(P, which restores the key-lever-locking bar to its normal andkeyloeking position. This same pushrod has thereon an arm 20, which isupwardly and rearwardly extended, the extremity of which, as seen at 22,is of wedge form.

23 represents a lever which is vertically hung by being intermediatelypivoted, as at 24, whereby it may have a swinging movement in a planeparallel with the direction of the shifting movement of the shiftabletagsupport 0, which it engages through means of the stud or projection25. This lever has its lower end in contact with and subject to thecam-operating impingement of the wedgeformed extremity 22 of theaforesaid arm, which is movable bodily with the push-rod G. Each timethe push-rod is rearwardly forced and temporarily held by a trigger torelease the locking-bar D, whereby one of a bank of keys may be operatedonce, the tag-support is given a shifting movement, so that a tag whichhas been sustained thereby will at once be permitted to drop to itsnormal and non exposed position.

The tag-support remains in its non-supporting position until a key-leverhas been fully depressed and starts back upon its return movement,whereupon the dog J trips the trigger and allows the push-rod G toresume its advanced position and the arm 20 to withdraw from itsposition which maintains the lever 23 so swung as to hold thetag-support in its non-supporting position, so that now the tagsupportby its spring a is moved into its tagsupporting position, this of courseoccurring before the key-lever has so far returned toward its normalposition as to permit the taglug b to pass below the tag-support.

I11 order to render the present device applicable upon cash-registeringmachines of the particular class shown in Patent No. 479,834, of July19, 1892, granted to J. J. Range, which have already been constructedand which may be in use, the arm 20 has at the base thereof the yoke orsaddle 27, which may set over and about an intermediate part of thepush-rod and be confined thereon by the set screw or screws 28.

Of course it is apparent from the statement of invention hereinbeforegiven and from an understanding of the improved device as considered inits primary aspect that the shifting device for the tag-support need notnecessarilybe combined with key-locking mechanism substantially asdescribed, although,

as has been described in detail, it has most advantageously acooperative combination therewith and it is the purpose more often to soemploy it.

In Figs. 5 and 6 the invention is substantially illustrated, the partsbeing combined and arranged thus: The push-rod G is connected directlyto the lever 23, which swings in a plane parallel to the length of thepushrod, and which rod has formed on or attached to its upper extremitythe canrfaced member 22, operating directly against the shiftablesupport-bar, and so in this mechanism also is found the combination ofshiftable tag-support, a rod independent of the operating register-keys, and a mediate device for moving the shiftable support byreason of the movement of the independent rod.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-

In a cash registering and indicating machine, the combination with theshiftable tagsupport, 0, and the lever, 23, engaging said support, ofthe push-rod, G, having thereon the device consisting of the yoke, 27,and the arm, 20, with the wedge-formed extremity, 22, and one or moreset-screws for confining said arm-provided yoke upon the push-rodwherebyits inclined end will have an opera tive impingement against saidlever, substantially as described.
